摘　　要：随着无人机、摄影相机及影像处理软件不断发展,以倾斜摄影实景三维模型的裸眼立体测图为主、传统垂直摄影立体测图为辅的作业方式逐渐成为大比例尺地形图生产的主要形式。针对同时采用两种立体测图方式作业存在的重复航摄效率较低或从五镜头相机提取下视影像成本较高的问题,结合具体工程实例,探索使用无人机单镜头进行倾斜摄影测量,在生成倾斜摄影实景三维模型进行裸眼立体测图的同时,从倾斜影像提取下视影像结合其空三加密成果进行传统垂直摄影立体测图。结果表明:该作业方式成本适中、航摄工作量小,生产的1︰500地形图精度满足相关规范要求。With the continuous development of Unmanned Aerial Vehicle(UAV),photographic camera and image processing software,the operation mode based on naked-eye stereo mapping of oblique photographic real-scene 3D model,supplemented by traditional vertical photographic stereo mapping,has gradually become the main form of large-scale topographic map production.Aiming at the problems of low efficiency of repeated aerial photography or high cost of extracting downward-looking images from five-lens camera when using the two stereo mapping methods at the same time,combined with specific engineering examples,this paper explores the use of UAV single lens for oblique photogrammetry,which generates the oblique photographic real-scene 3D model for naked-eye stereo mapping,and at the same time extracts the downward-looking image from the oblique image combined with the results of aerial triangulation encryption to perform traditional vertical photographic stereo mapping.The results show that the cost of this method is moderate the workload of aerial photography is small,and the accuracy of produced 1︰500 topographic maps meets the requirements of the relevant specifications.
